       4. The testing method for the display panel of  claim 2 , wherein the step of testing the display panel according to the preset time is to test the display panel according to a duration of each default image, a display sequence of each default image, and a number of times of each default image. 
     
     
       5. The testing method for the display panel of  claim 1 , wherein the step of testing the display panel according to the preset test condition is to test the display panel according to a preset voltage and a preset current. 
     
     
       6. The testing method for the display panel of  claim 1 , wherein the step of testing the display panel according to the preset test is to test the display panel according to a preset time, a preset voltage, and a preset current. 
     
     
       7. The testing method for the display panel of  claim 1 , before retrieving the image signal, further comprising:
 detecting a test signal, and after the test signal is detected, providing the power and clock signals required by the display panel, and retrieving the image signal. 
 
     
     
       8. The testing method for the display panel of  claim 1 , further comprising:
 retrieving the image signal and combining the clock signal to convert the image signal into a display control signal; and 
 driving the display panel to display the default image based on the display control signal. 
 
     
     
       9. The testing method for the display panel of  claim 8 , wherein the step of driving the display panel to display the default image based on the display control signal is to drive the display panel to display a plurality of different default images based on the display control signal, wherein each default image has a corresponding duration, a corresponding display sequence, and a corresponding number of display times. 
     
     
       10. The testing method for the display panel of  claim 1 , further comprising:
 measuring and recording a performance parameter of the display panel. 
 
     
     
       11. The testing method for the display panel of  claim 10 , wherein the step of measuring and recording a performance parameter of the display panel is to measure and record a luminance and/or a resolution of the display panel. 
     
     
       12. The testing method for the display panel of  claim 1 , further comprising:
 real-time measuring and recording a performance parameter of the display panel. 
 
     
     
       13. The testing method for the display panel of  claim 1 , wherein the power and clock signals are provided to the display panel by an external power board. 
     
     
       14. A display device, comprising:
 a control device, configured to store an image signal for controlling a display panel to display a default image, 
 wherein the control device is further configured to connect an external power and a clock signal to provide a power and the clock signal to the display panel, and 
 the control device is further configured to retrieve the image signal without using a timer-control-register board and test the display panel based on the image signal and the clock signal according to a preset test condition; and 
 the display panel, which is configured to display the default image based on a control of the control device. 
 
     
     
       15. The display device of  claim 14 , wherein the control device is configured to retrieve the image signal and covert the image signal in to a data voltage and drive the display panel to display the default image based on the data voltage and the clock signal. 
     
     
       16. The display device of  claim 14 , wherein the control device is further configured to store the image signal for controlling the display panel to display the default image; and connect the external power and the clock signal to provide the power and the clock signal to the display panel; and retrieve the image signal and test the display panel based on the image signal and the clock signal according to the preset test condition; and display the default image based on a control of an execution module. 
     
     
       17. The display device of  claim 16 , wherein the control device is further configured to retrieve the image signal and convert the image signal into a data voltage; and drive the display panel to display the default image based on the data voltage and the clock signal.
